r275234 addressed sort automatically converting 8-bit locales to UTF-8
by using "LANG=C sort", but LC_ALL overrides LANG if set, so the issue
may still be present depending on the user's environment. Use LC_ALL=C
instead.

The blacklistd daemon keeps records of failed login attempts for
each address:port that is flagged as a failed login. When a
successful login occurs for that address:port combination,
the record's last update time is set to zero, to indicate no current
failed login attempts.
Reset the failed login count to zero, so that at the next failed
login attempt, the counting will restart properly at zero. Without
this reset to zero, the first failed login after a successful login
will cause the address to be blocked immediately.
When debugging is turned on, output more information about database
state before and after the database updates have occured.

data structures.
vt_change_font() calls vtbuf_grow() to change some vt driver data
structures. It uses TF_MUTE to prevent the console from trying to use those
data structures while it changes them.
During the early stage of the boot process, the vt driver's tc_done routine
uses those data structures; however, it is currently called outside the
TF_MUTE check.
Move the tc_done routine inside the locked TF_MUTE check.

The MIPS ABI does not require the second GOT entry to be reserved for use
by the runtime linker as on other architectures. Instead, static linkers
use a special value in the second GOT entry to indicate if the entry is
reserved. This value is supposed to consist of an address with the MSB
set and the rest of the bits all zero which is an invalid user address.
However, the old binutils currently in the tree uses the 32-bit mask value
(2^31) on 64-bit MIPS instead of 2^63. This was fixed in upstream
binutils in 2008 to use 2^63 on 64-bit MIPS.
The first part of this change changes the runtime check in init_pltgot()
to check for both values (2^31 and 2^63) when deciding whether to store
the current object pointer in GOT[1] which fixes dynamic N64 binaries
compiled with modern binutils.
However, the initial version of this fix exposed another related bug in
that _rtld_relocate_nonplt_self() was only checking for the new value
(2^63) in GOT[1] and incorrectly treated GOT[1] as a local GOT entry
(and did not relocate the final local GOT entry). To handle this, fix
all of the places that check for GOT[1]'s status to use the same macro
that checks for both values on N64.

When blocking an address, the blacklist-helper script
needs to do the following things for the ipfw packet
filter:
- create a table to hold the addresses to be blocked,
so lookups can be done quickly, and place the address
to be blocked in that table
- create rule that does the lookup in the table and
blocks the packet
The ipfw system allows multiple rules to be inserted for
a given rule number. There only needs to be one rule
to do the lookup per port. Modify the script to probe
for the existence of the rule before attempting to create
it, so only one rule is inserted, rather than one rule per
blocked address.

For example, the FreeBSD GCC (4.2.1) has a spotty support for that
feature. If the static keyword is used with an unnamed array parameter
in a function declaration, then the compilation fails with:
error: static or type qualifiers in abstract declarator
The feature does work if the parameter is named.
So, the restriction introduced in this commit can be removed when all
affected function prototypes have the workaround.

Restricting stdio before actually opening the files prevent trying to raise the

if the fdt data doesn't provide a gpio pin for reading the write protect
switch and also doesn't contain a "wp-disable" property.
In r311735 the long-bitrotted code in this driver for using the non-
standard fdt "mmchs-wp-gpio-pin" property was replaced with new common
support code for handling write-protect and card-detect gpio pins. The
old code never found a property with that name, and the logic was to
assume that no gpio pin meant that the card was not write protected.
The new common code behaves differently. If there is no fdt data saying
what to do about sensing write protect, the value in the standard SDHCI
PRESENT_STATE register is used. On this hardware, if there is no signal
for write protect muxed into the sd controller then that bit in the
register indicates write protect.
The real problem here is the fdt data, which should contain "wp-disable"
properties for eMMC and micro-sd slots where write protect is not even
an option in the hardware, but we are not in control of that data, it
comes from linux. So we have to make the same flawed assumption in our
driver that the corresponding linux driver has: no info means no protect.
